The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Embodiment 1:

[0034] A high-pressure water gun testing device comprises a controller, a pressure gauge 3, a test bench 1, a high-pressure water gun 2, a fixing mechanism, an actuator, a gun rod automatic insertion mechanism, a water outlet mechanism, a water inlet mechanism and a water storage mechanism, wherein:

[0035] The controller is a common PLC controller in the prior art, so it is not elaborated in detail here;

[0036] The pressure gauge 3 is a pressure gauge 3 available on the market in the prior art that can measure pressure, so it is not described in detail here;

[0037] The high-pressure water gun 2 is a product to be tested in this application, including a butt, a gun body, a trigger and a gun rod. The butt is provided with a water inlet, and the gun rod is docked and matched with the test rod 9;

[0038] The fixing mechanism is mainly used to fix the high-pressure water gun 2 to be tested, and includes a plurality of fixing seats 4 for the high-pressure water gun 2 to be embedded and fixed, and a water inlet rod 5 for inserting into the water inlet of the high-pressure water gun 2, and the fixing seat 4 includes a fixing block 12 for the high-pressure water gun 2 to be embedded and installed, a connecting block 13 connected to the back of the fixing block 12, and a mounting block 14 connected to the connecting block 13 and sleeved on the outside of the water inlet rod 5, and the fixing mechanism also includes a mounting seat 15 fixed on the test bench 1, an elastic member 16 is arranged between the mounting block 14 and the mounting seat 15, and the elastic member 16 is a spring in this embodiment, and a limit member 17 is also arranged between the mounting seat 15 and the mounting block 14, and the limit member 17 is a bolt in this embodiment. The lower part of the bolt is fixed on the mounting seat 15, and a through hole for the bolt to pass through is provided on the mounting block 14, and the size of the bolt head is larger than the size of the through hole, so that the bolt head cannot pass through the through hole, that is, the mounting block 14 can be well prevented from being separated from the mounting seat 15, and the spring is sleeved on the limiter 17, so that the mounting block 14 can be pushed away from the mounting seat 15 by the spring. When there is no external force, the upper end of the mounting block 14 is always against the bolt head. When an external force is applied, the mounting block 14 will be pressed downward, and then the fixing block 12 will be pressed downward together, so that the high-pressure water gun 2 embedded in the fixing block 12 can be pressed downward, so that the water inlet rod 5 can be installed into the water inlet of the high-pressure water gun 2;

[0039] The actuator is mainly used to drive the trigger of the high-pressure water gun 2 to be tested to move, so as to realize the automatic test of the high-pressure water gun 2. It includes a push block 8 for driving the trigger of the high-pressure water gun 2 to move, and a first power mechanism 23 for providing power to the push block 8. The push block 8 is a round rod, and a slide groove 18 is provided on the fixed block 12. The round rod can slide in the slide groove 18, and one end of the round rod is connected to one end of a transmission member 19, and the other end of the transmission member 19 is connected to the power part of the first power mechanism 23. In this embodiment, the first power mechanism 23 is a cylinder, that is, the other end of the transmission member 19 is connected to the piston rod of the cylinder, so that when the cylinder drives the piston to move, it will drive the transmission member 19 to move, thereby driving the push block 8 to move in the slide groove 18, and realizing the control of the trigger movement of the high-pressure water gun 2;

[0040] The automatic gun barrel insertion mechanism is mainly used to drive the test rod 9 to be inserted into the gun barrel for testing. It includes the test rod 9 for inserting into the gun barrel and a second power mechanism 24 for providing power to the test rod 9. It also includes a test seat 20 and a connecting member 21 fixed on the test seat 20. The action part of the second power mechanism 24 is connected to the connecting member 21. In this embodiment, the second power mechanism 24 is a cylinder, that is, the piston rod of the cylinder is connected to the connecting member 21. In this way, when the second power mechanism 24 works, it can push the connecting member 21, and then push the test seat 20, driving the test rod 9 to move forward and insert into the gun barrel to achieve matching;

[0041] The water storage mechanism includes a water storage bucket disposed below the test bench 1, which is used to receive water flowing out of the water outlet mechanism and to supply water to the water inlet mechanism;

[0042] The water inlet mechanism includes a pressure pump for pumping water from the water storage mechanism, a water inlet pipe 6 for conveying the pumped water to the water inlet rod 5, and a one-way valve 7, wherein the inlet of the one-way valve 7 is connected to the water outlet of the water outlet pipe 10, and the outlet of the one-way valve 7 is respectively connected to the water inlet rod 5 and the pressure gauge 3, wherein the one-way valve 7 and the pressure pump are both commercially available products of the prior art, so they are not elaborated in detail here;

[0043] The water outlet mechanism includes a water outlet pipe 10 connected to the test rod 9, each test rod 9 is connected to a water outlet pipe 10, and then multiple water outlet pipes 10 are connected to a main pipe, and the water outlet of the main pipe faces the water storage barrel, so that the water flowing out of the water outlet pipe 10 will directly flow into the water storage barrel;

[0044] The working principle of the present application is: first, the user puts the high-pressure water gun 2 into the fixed block 12, and then presses the fixed block 12 downward. At this time, the fixed block 12 will drive the high-pressure water gun 2 and the mounting block 14 to move downward. Because the water inlet rod 5 is stationary, the water inlet rod 5 will be inserted into the water inlet of the high-pressure water gun 2 to achieve installation matching; then the second power mechanism 24 is controlled to drive the test seat 20 to move, so that the test rod 9 set on the test seat 20 is inserted into the gun rod to achieve matching; then the pressure pump works to pump the water in the water storage tank 11 to the water outlet pipe 10, and then enters the water inlet rod 5 and the pressure gauge 3 after passing through the one-way valve 7. For a period of time, check whether the high-pressure water gun 2 will leak after water is ingested. If there is no leakage, continue to control the first power mechanism 23 to work, drive the trigger of the high-pressure water gun 2 to move, and realize opening the high-pressure water gun 2, and then water will spray out from the test rod 9, flow to the water outlet pipe 10, and finally flow back to the water storage tank to achieve a test.

[0045] Embodiment 2:

[0046] The difference from the first embodiment is that the automatic gun barrel insertion mechanism of the second embodiment also includes a rotating mechanism, which includes a rotating block 22 fixed on the test rod 9 and a third power mechanism 25 for driving the rotating block 22 to rotate. The third power mechanism 25 is also a cylinder, and the bottom of the cylinder is rotatably connected to the connecting piece 21, and the piston rod of the cylinder is rotatably connected to the rotating block 22. In this way, when the cylinder is working, it can pull the rotating block 22, thereby driving the test rod 9 to rotate, that is, when the test rod 9 is inserted into the gun barrel, the test rod 9 is rotated again to lock the test rod 9 on the gun barrel, so that during testing, the test rod 9 is not easy to detach from the gun barrel.

[0047] Embodiment three:

[0048] The difference from the first embodiment is that the water inlet mechanism in the third embodiment also includes a clean water pump, which is used to pump water into the water inlet pipe 6. Because it does not require a lot of pressure to pump the water in the water storage tank into the water inlet pipe 6, an ordinary clean water pump can be used. However, it requires pressure to input the water in the water inlet pipe 6 into the water inlet rod 5, so a pressure pump is needed to achieve this. This can greatly improve the test efficiency and does not increase the cost much.
